LIQUID PRODUCTSv MIXING APPARATUS Filed oct'. 12, 1964 5 sheets-sheet s ATTORNEY@ United` States Patent z claims. (ci. 266-34) In usual metallurgical process, it is often required for accomplishing in a short time an equilibrium or reaction of metals to effect a suicient mixture between molten products, for example, betweenv two kindsr of metals or between Ia kind of metal and slag.

The present invention relates to an apparatus chiey developed for accomplishing such purpose as above, and is more particularly directed -to an improvement in such an apparatus that liquid products contained in two pots are violently mixed by being transferred :alternately by means of the top pouring from a position having a predetermined head. According to the present inven tion, there is provided a mixing apparatus characterized in that two pots containing products to be mixed are removably mounted in respective holder rings, and these rings are in right and left relationship supported to hang by a balance type frame, and there are arranged means for tilting the balance type frame for moving the two pots up and down alternately, and means for tilting the holder rings in relation to the balance type frame.

In order that the present invention may be clearly understood and readily carried into effect, the same will now be explained with reference to and by the aid of the accompanying drawings, wherein:

FIG. 1 is a side elevational view of one embodying apparatus according to the present invention,

FIG. 2 is a top plan view thereof,

FIG. 3 is a diagram showing the construction of a balance frame tilting mechanism and of a holder ring inclining mechanism.

FIG. 4 is a diagram showing the operation of the holder ring tilting mechanism,

FIGS. 5 to 10 are explanation diagrams of the process of operation for pots.

Referring to the drawings, numerals 1a and 1b denote a pair of holder rings in which respective pots 2a and 2b are detachably mounted, and numeral 3 denotes a balance frame supporting in right and left relationship the two holder rings 1a and 1b, each ring being pivotally supported thereby at its respective axis 4a or 4b. A center shaft 5 provided on both side surfaces of the frame 3 is pivotally supported by an installation base 6. On either side of the frame 3, there is provided Ia mechanism A for tilting the balance frame 3 for moving the two pots 2a and 2b up and down alternately, which mechanism A comprises, as clearly shown in FIG. 3, a pair of oil pressure cylinders 7a and 7b xed to the installation base 6, a rack provided ram 8 contained therein, and a pinion 9 meshed with the rack and attached to the center shaft 5 of the frame 3. 'The two mechanisms A and A are arranged on both sides of the frame 3 in the embodiment shown on the drawings, but it can be modified that only one mechanism A is arranged on one side of the frame. On one side of the fname 3, there is also provided a mechanism B for inclining laterally the upper position or lower position pot by inclining the corresponding holder ring when either of the two pots Za and 2b has reached its upper limit position. This mechanism B comprises, as clearly shown in FIG. 3 a pair of oil pressure cylinders 10a and 10b having respective rods 11a and 11b pivoted at 12 at their inner ends, and a 3,334,884 Patented Aug. 8, 1967 ICC third oil pressure cylinder 13 having a rod 14 connected to a cover of the oil pressure cylinder 10a. The axis 4a and 4b have respective arms 15a and 15b, and the mechanism B constructed as above is pivotally connected at its both ends by pins 16a and 16b to the respective Aarms 15a and 15b. It can be modied that two of such mechanism B are prepared and arranged on both sides of the frame 3, though such is not illustrated.

For the operation of the apparatus, the two pots 2a and 2b are charged, for example, with molten bath from an electric furnace by means of a crane or the like, and after the measurement of the net weight of the molten bath the two pots 2a and 2b are removably mounted in the respective holder rings la and 1b. At this time, the oil pressure circuit for the oil pressure cylinders 7a and 7b is closed for keeping ontow and inflow of oil in its stop condition, so that the balance typeframe 3 may be kept horizontal as shown in FIG. 5 or by full lines in FIG. 3. lf, from the condition, pressure cylinders 7a .and 7b, for example, the cylinder 7b to move the ra-m 8 to the left, the pinion 9 engaging therewith is turned clockwise and through the center shaft 5 the balance type frame 3 is inclined in clockwise direction as shown by an arrow. Accordingly, the pot 2a is moved upwardly while the pot 2b is moved downwardly as shown in FIG. 6. In order to keep the pots 2a and 2b always horizontal during this oper-ation, it is needless to say that the axis 4a and 4b must be disposed -above the center of gravity of the respective pot. The inclination angle and speed can be settled at will by the inflow amount and speed of oil, and this can be effected by opening and closing an electromagnetic valve, not shown.

When the inclination of the balance type frame 3 has been stopped at the position shown by full lines in FIG. 4, the oil pressure cylinder 10a corresponding to the pot 2a situated at the upper limit position is applied with compressed oil, whereby the cylinder 10a moves towards the point 12 and at the same time the oil pressure cylinder 13 follows the same keeping its relative position with the cylinder 10a to pull the arm 15a, as shown by dotted lines in FIG. 4. AsV a result thereof, the axis 4a turns clockwise as shown by an arrow and only one side holder ring 1a is turned laterally under .the condition where the pot 2a is mounted therein as shown in FIG. 7. Thus, the molten bath contained in the pot 2a is poured into the other pot 2b disposed just below the pouring mouth of the pot 2a.

After the completion of the pouring into the pot 2b, the holder ring 1a is returned to its horizontal position by reversely operating the oil pressure cylinder 10a, and then the frame 3 is returned to its horizontal condition as shown in FIG. 5 by reversely operating the cylinders 7a and 7b. Then, almost the same operation as mentioned above is carried out with the other pot 2b also, as shown in FIGS. 8 and 9. These operations are repeated. After the mixing process has finished, the mixed molten bath contained in the pot 2a is poured in a vessel 17 by the following operation:

Namely, under the condition that the frame 3 is kept inclined to the position shown by broken lines in FIG. 4, if the third oil pressure cylinder 13 is applied with compressed oil, the oil pressure cylinder 10a is kept in its position as it is and only the cylinder 13 moves outwardly to become more distant from the cylinder 10a as shown by dotted lines. Accordingly, the holder ringA 1a under the condition that the s-a-me supports the pot 2a is inclined outwardly so that the pot 2a lis laterally inclined outwardly, for permitting the bath therein to pour outwardly. In this case, by the composition of the inclining motion of the balance frame 3 and the outward pouring motion of the holder ring 1a, the pouring head of the molten bath can be kept at the minimum to make the operation smooth.

As the apparatus of the present invention is so constructed as above, the moving locus of each pot is formed only by the movement of the pot itself, and any such construction member occupying space as rails or the like as seen in the connected apparatus of this kind is not required. Accordingly, the installation position of t-he apparatus can be selected at Will and the smooth operation can be always expected. As for the function of mixture for molten bath, it is generally required that molten bath is poured violently. Accordingly, it is desired that for nding out the most suitable pouringspeed the adjustment of the pot for corresponding thereto can be carried out. According to the present invention, adjustment of the pouring speed can be achieved very easily and an automatic driving system for the apparatus can be designed to be very simple.
